"I killed the revellers near Falkreath because I thought they were bandits. Even worse, I left one of them alive because I realized my mistake. He never knew who killed his happy drunk friends." - PatsyDragon

"For whatever reason, this is what I feel the worst about doing: I had a giant spawn near my Falkreath house during my second to last playthrough. Instead of killing him, I named him Roger and went out of my way to not aggro him when I was outside. Whenever I would get home from a week's worth of adventuring, Roger was always there to greet me with an arm wave and club shake. I miss Roger.

"Sacrificing Lydia to Boethiah to complete the quest. I didn't feel too bad about it at first because, you know, it was Lydia. But shortly after a courier gave me a note saying she'd left me 100 gold in her will, and that made me feel like a jerk." - JangoF76

"I recently managed to convince the Caller in Fellglow Keep to let me take the books and go without a fight. As soon as I grabbed them all, I walked around her and killed her with a well placed arrow to the back of the head." - Denimjo

"I broke into a house, found a sleeping couple, and cast fury on them both until one killed the other. The survivor didn't see me and I crept out again. I totally framed a man for the murder of his wife." - Just_Dandy

"Ever since getting the Mace of Molag Bal I've had a taste for killing priests. So far I've skullbashed the dude near the Shrine of Talos in Whiterun, and decapitated one in Riften. I think I might have a problem."
